Optical pickup transferring apparatus of an optical disk drive

摘要

An optical pickup transferring apparatus including a slider having a base, a floating portion elastically coupled to the base, the floating portion having on one side thereof at least one protuberance inserted into the external thread of a lead screw, and an elastic element located on the top of the base and the floating portion. The elastic element includes a first elastic portion to push the floating portion toward the lead screw so that the protuberance is inserted into the external thread, and a second elastic portion to push the floating portion toward the screw groove to thereby prevent the protuberance from escaping from the external thread when the floating portion is transformed elastically.
